Creating the /etc/inputrc File
Readline and inputrc
How do I convert inputrc settings to bashrc ones?
The
/etc/inputrc
file deals with mapping the keyboard for specific situations. This file is the start-up file used byreadline
, the GNU command line editing library used byBash
,perl
and most other open source programs.
